SHEAF-CARRIER.

SPECIFICATION forming part of Letters Patent No. 418,222, dated December 31, 1889. Application filed September 15, 1888. gerial No. 285,528. (No model.)

To all whom it may concern.- therefrom when the carrier is in its receiv- Be it known that I, HENRY E. PRIDMORE, a ing position and automatically opened and citizen of the United States, residing at Chibrought parallel with said slat as the carrier cago, in the county of Cook and State of Illiis swung to the rear to permit the discharge 55 nois, have invented certain new and useful of the sheaves.

In such, however, so far carrier. as I am aware, the individual slats or fingers A represents the rear platform-sill, and A 8 5 were merely brought to a parallel or nearly the rear elevator-sill; B, the front platformparallel position concurrently with their sill and finger-bar, and B the front elevatordrooping movement and did not shut in past sill of a harvester, these sills, except the front each other. platform-sill, being herein shown as formed In my present invention I propose to conof square pipes, as are also the cross-girts of 0 40 struct the carrier of two or more independthe elevator-frame, but this form being secntly-pivo'ted fingers, slats, or boards swinglected only as an exponent of any suitable ing in different horizontal planes and so arconstruction. ranged that when swung back they will shut C is the main wheel, and D the outer girt, in one beneath the other, bringing them into and E represents the grain-deck receiving 5 parallelism with the line of advance of the from the elevator E, and having at its foot machine and causing each overlying board to or discharge end a tail-board E as usual in become a stripper or ejector for the load on modern grain-binders. Automatic binding the next underlying. I further propose to mechanism will of course be located over and apply to the outer end of one or more of these beneath this grain-deck; but I have not [00 individual slats or boards a pivoted guard or deemed it necessary to show any in the drawtail-picce rising vertically or nearly vertically in gs.

Brackets F are bolted to the outside girt D of the frame and project therefrom at different heights, the one to the front being the lowest. These brackets are further supported near their outer ends by means of brace-rods F, hooked over a bar or gas-pipe F carried upon the outside elevator-struts some height above the sill-frame, which pipe may be one of the supports for the binder attachment. To the outer ends of these brackets is secured a slightly-inclined bar G, ascending from front to rear and having its length parallel or practically parallel with the line of advance of the machine, and its face perpendicular, or nearly so, to the ground.

The biackets and the bar which they support are in the presentconstruction intended to be of metal, but may of course be of wood, to less advantage, however.

The bar G, which may be termed the carrier-frame bar, has secured to its face at suitable intervals a number of vertical bearingboxes H, which, owing to the inclined position of the bar G, will he stepped one above the other, as shown in Fig. 4, the lowest being at the front and the highest at the rear. For the purpose of the present description three such boxes have been shown, but a greater number may be provided, if desired, or even two may be sufficient. Into these bearing-boxes enter pivots H, rising from plates 72, bolted to the inner ends of boards or slat-s 11*, which latter form the supporting-surface of the carrier. In order to better support the slats and prevent their sagging, they are further united to the upper ends of the pivots, after the latter have been inserted in their bearings, by means of metal straps h, bolted at their lower ends to the slats some distance fro-m the pivot, and at their upper ends taking over the pivot-pins above the bearings and held thereon by the securing cotters or keys, which retain said pivot-pins in the bearings.

The pivot-plates have insetting spurs h which are connected beneath the supportingbrackets by a single rod or bar H so that when this rod or bar is moved back and forth it will swing the slats around on their pivots either into position to receive or into position to discharge-that is, when the rod is moved to the front it will swing each slat to the rear; and since the pivot of each individual slat is in line with the pivots of the others and each forward slat is lower than the one to the rear the slats will shut in under each other parallel with the line of advance of the machine, and depending on the position of their supporting-bar, entirely or almost entirely beneath the decking, thus taking up no additional space whatever over that demanded by the machine to which they are attached. In this rearward movement it is obvious that each hinder slat, shutting over each forward and lower one, will tend to push its load off. Thus the carrier becomes selfstripping.

The movement of the carrier is controlled from the drivers seat by means of along bellcrank I, mounted in a bearing 2' at the forward end of the bar which supports the carrier, and also at the other end in a bearing 1" on a bracket i projecting from the seat-plank of the machine or over a suitable part of the frame. The crank i at that end adjacent to the carrier is connected by a link I with the operating-rod pivoted to the spurs from the carrier pivot-plates, while the crank i at the other end receives one end of a foot-bar 1 extending rearwardly over the seat-plank and journaled upon a wrist-pin from one arm 70 of a small bell-crank K, the other arm is of which extends to the rear alongside the inner edge of the seat-plank, and has a foot-piece 7c ,which,when depressed, draws the bar to the rear and sets the slats in position to receive from the binder, while a push by the foot upon the end of the bar carries it to the front and swings the slats back to shut past each other and discharge the bundle.

It Will be observed by reference to Fig. 4. that while the rear slats are horizontal when viewed in transverse section, the front slat, or that which receives the butt-end of the sheaf, is inclined transversely toward the rear and the ground. This I have found desirable and practically effectual for the purpose of preventing the load from creeping forward and falling oif of the carrier.

In order to guard against any tendency of the sheaves to roll off over the ends of the slats, a tail-piece L is pivoted to the outer end of a central slat, although it will be understood that the other slats may have a similar tailpiece if for any purpose desired. A downhanger Z from said tail-piece is connected by a link Z with the carrier-supporting bar at a point somewhat in advance of the pivot of the particular slat, so that whenever the slat is swung to the rear the link shall draw upon the lug and cause the tail-piece or guard to swing down until it becomes parallel with the slat, so that not only may the load be discharged but the slat be able to pass beneath the ones to the rear. Vhen swung forward again, the-link will push upon the lug and swing the tail-piece up again to the vertical position.

It will be understood that I do not intend to limit myself to the precise and specific construction herein described, since it is obvious that many changes may be introduced into the frame-work and even into the controlling and operative mechanism without departing from the spirit of my invention. For instance, instead of arranging the carrier-supporting bar or frame-bar at an inclination, it may be placed horizontally fore and aft, as in Fig. 9, where G represents said bar, and while the pivot for the rear slat or arm H of the carrier is vertical the pivots for the forward slats or arms may be just sufficiently inclined to cause them to shut beneath the rear ones when swung back to discharge, as in Fig. 9, and such arrangement has the effect to slightly tilt the forward slats transversely when in their receiving position without primarily arranging them obliquely to their pivots, as is the case with the forward slat in the first-dscribed construction.

In Fig. 10 the carrier-frame bar is still slightly but not so much inclined as in the first construction, and the two rear arms are mere rods or fingers swinging on vertical pivots and shutting up against and parallel with each other. The next arm in advance is coinposed ofa slat and swings, also, on avertical pivot, which may be in line with the others to bring this arm parallel with and beneath the two to the rear when swung back, as in Fig. 10, and the front arm may either be on a dropped pivot, as in Fig. 4, or on an inclined pivot, as shown, to cause it to shut beneath the others to the rear and at the same time be tilted transversely to prevent the sheaves from traveling to the front. In the latter two figures the lever-arms or insetting spurs of the fingers are longer than those from the slats. Therefore the bar I-I is jointed at the pivots, as shown, to permit a knuckling movement.

Other modifications will readily suggest themselves to those skilled in the art.

I claimi- 1. The combination, substantially as hereinbefore set forth, to form a sheaf-carrier, of

a series of normally-parallel slats or fingers, individual pivots for each finger, arranged practically as described, that the forward fingers may be closed beneath those to the rear, and a common actuating device for all the fingers.

2. The combination, to form a sheaf-carrier, and with the grain-deck of an automatic grainbinder, of a series of slats or fingers normally parallel with the line of delivery of the deck and with the slot at the butt or forward end at an inclination transversely, individual pivots for each finger, arranged practically as described, that the forward fingers maybe closed beneath those to the rear, and a common actuating device for all the fingers, whereby they are swung in unison.

3. The combination, to form a sheaf-carrier, of a series of slats or fingers normally parallel with the line of reception, an independent vertical pivot for the rear slat or finger, and independent upstanding pivots for the remaining slats, arranged practically as described, whereby they are successively shut beneath the others when swung to said discharge position.

4. The combination,in a sheaf-carrier, of a series of slats or fingers normally parallel with the line of reception, independent pivots for each slat, a common controlling device, whereby they are swung on said pivot-s toward a closing-point, an upstanding guard or tail-piece hinged to the outer end of one of said slats, and a link connecting said guard with the supporting-frame at a point eccentric to the pivot of the individual slat, whereby the guard will be thrown down as the carrier is swung from the receiving to the dumping position.

5. The combination, with the harvesterframe and with the binder, of the inclined carrier-frame bar, the series of upstanding bearings stepped thereon, those to the rear higher than those in front, the series of carrier-fingers pivoted in said bearings, the operating-bar connected to spurs from the inner end of said fingers, and a lever whereby said bar is actuated.

6. The combination of the frame-bar G, the bearings H, the pivots H, the slats or fingers H the operating rod or bar H the hingeguard L, and the link Z, substantially as described.
